I posted a similar question last year after a MJ1200 lost suction and fell down blowing my sand everywhere. I have a 4" DSB
and my nitrates went through the roof. For several reasons I've had nitrate issues, and I finally seem to have resolved them (got them down from over 50 to 2.5) - well, today I came home to the same MJ1200 dispite me replacing suction cups last year fallen and blowing sand everywhere.
My nitrates were 2.5 yesterday BEFORE I did a water change - they are now somewhere between 10 and 20. I know that sandstorms can do this when an established deep sand bed is disturbed (tank has been running for a little over a year) - but, I also checked my pH and I'm getting a reading of 8.0. It is consistantly 8.2. I'm not overly concerned (yet), but would this sandstorm also affect my pH levels?
Just when you thought it was safe to add fish to your water....
